HENRY E. HAYDEN, OF \VASHINGTON, DISTRICT OF COLUMBIA, ASSlGNOR TO THE INTERNATIONAL VAPOR, FUEL AND CARBON IRON AND MANU- FACTURING. COMPANY, OF SAME PLACE.

APPARATUS FOR GENERATING VAPOR FROM LIQUID HYDRO CARBONS.

SPECIFICATION forming part of Letters Patent No. 279,154, dated June 12, 1883. Application filed June 11, 1581. Renewed March 26,1883. (No model.)

To all whom it may concern:

Be it known that l, HENRY 1*. HAYDEN, a citizen ofthe United States of America, residing at \Vashington, in the District of Columbia, 5 have invented certain new and useful Improvements in Apparatus for Generating Vapor from Liquid Hydrocarbons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to that class of vaporgenerators in which steam is used for causing the vaporization of liquid hydrocarbons; and the nature thereoiconsists in certain improvements in the construction of the same and novel combination of parts hereinafter shown and described.

Having reference to the accompanyin drawing, B designates the retort or chamber in which the vapor is generated, consisting of 2 5 two or more communicating spheroidal receivers surrounded by a jacket, A, which forms a steam-space, X, between the superheater and the said spheroidal receivers, 'connnunicating by means of the pipe Y, having the valve E,

0 with the steam-supply pipe Z. The steamsupply pipe Z is provided with valves H and G, and communicates with a superheatcr, V, arranged in the space between the jacket A and the casing, through which the heated gases 5 or products of combustion pass from the furnace S to the smoke-pipe. The superheated steam passes from superheater V through the pipe K, providedwith a suitable valve to the pipe 0, having avalve, J, and through the lat- 0 ter pipe to the generator B.

The liquid hydrocarbon is supplied to the generator by means of the pipe D, having the valve L, and the vapor generated passes to the point where it is to be used through the pipe 4 5 E, provided with pyrometer I and valve M.

The steam-space X may also be used as a steamgenerator by providing a water-tank supplied by a pipe, 0, having a suitable valve for regulating the flow of the water.

This watentank communicates by means of the pipes 0 0, each of which have suitable valves, with the steam-space X. Theheat imparted to the jacket A by the escaping products of combustion causes water introduced through either the pipe 0 or the pipe 0 to be vaporized, and the steam thus produced may be carried through the pipe Y to the steamsupply pipe Z. A

The. operation of the apparatus is as follows: The requisite amount of steam is admitted through the pipe Z to the superheater V and the steam-space X. The steam admitted to the steam-space imparts its heat to the exterior ot' the generator B, while the steam admitted to the superheater is superheated and flows through the pipes K and G to the bottom of the generator B, where it comes in contact with the liquid hydrocarbon, which enters through the pipe 1). The arrangement of the spheroidal receivers is such as to cause the upward current of steam to spread and divide the downward current of liquid hydrocarbons and to cause their evaporation according to their volatilitythat is to say, the most vola tile hydrocarbons are evaporated first and the least volatile last-while the carbonaceous residua of the hydrocarbons thus vaporized will be attacked by the highly-heated steam and carbonic oxide and hydrogen gas formed.

It the space X is used as a steam-generator, instead of admitting steam from the pipe Z, the valve H is closed and the valve 0 or o, communicating with the tank N, is opened. \Vater will then fiowinto the space X, and, being transformed into steam, will pass through the opened valves E and G to the super-heater.

Having thus described my invention, I claim and desire to secure by Letters Patent, ot' the United States 1. I11 the apparatus for generating vapor from liquid hydrocarbons herein described, a generator composed of two or more communicating spheroidal receivers,- a pipe for the direct introduction of steam into the generator, and a chamber surrounding the generator, which may be used either as a steamspace or steam-generator, all combined as and for the purpose described.

2. In an apparatus for generating vapor from liquid hydrocarbons, the combination of the spheroidal receivers, the chamber X, tank N, andcommunicating pipes 0 0, as and for the purposes described.

8. In an apparatus for generating vapor from liquid hydrocarbons, the combination of the retort or generating-chamber composed of two or more communicating spheroidal receivers, and a pipe for the direct introduction of steam into thegenerator. I

4. The combination of the generator B, consisting of two or more communicating spheroidal receivers, pipe D, for supplying the liquid hydrocarbons, pipe C, for admitting steam, pipe E, for carrying away the Vapor, and superheater V, as and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY F. HAYDEN.
